A turning loop is an often circular road segment at the end of a road that is used for turning around, similar to a highway=turning_circle but with a non-traversable traffic island in the middle, which may be higher or lower than the surrounding roadway. Unlike a junction=roundabout or highway=mini_roundabout, only one road connects to it (other than driveways and service roads).
This tag was originally created because some mappers found it more convenient to map a node than a loop but were misusing highway=mini_roundabout. [1] The standard tile layer renders highway=turning_loop the same as highway=turning_circle. [2]
How to map
There are two methods for mapping a turning loop, either of which is valid:
- Tag the node at the end of a
highway=*way with thehighway=turning_looptag. The node should be located in the middle of the traffic island. - Draw a closed
highway=*way around the traffic island and connect it to the main road, giving it the same name. If traffic is required to flow in a particular direction around the traffic island, addoneway=yes. This method is preferred for large turning circles, because navigation applications decide whether the user is on- or off-route based on their distance from the roadway. This method also makes it possible to accurately map features inside the loop, such as parking spaces, trees, or a flagpole.
If a turning loop has been mapped as a way, do not remap it as a simple node, as that would remove detail from the map.
